BRICKMAKING-MACHINE.

Specification of Letters Patent.

Patented Dec. 4, 1906.

T0 on whom it may concern.-

Be it known that we, JosEPH WELLING- TON FERGUSON and GEORGE WELsH FERGU- soN, brickmakers, subjects of the King of Great Britain and Ireland, residing at Sydney Road, Wangaratta, in the county of Moira, State of Victoria, Commonwealth of Australia, have invented certain new and useful Improvements in Brickmaking-Machines, of which the following is a specification.

The object of our invention is to provide a cheap and effective machine for making bricks for building or other purposes.

Referring to the drawings which form a part of this specification, Figure 1 is a plan of our machine. Clay has filled the feed-hopper and portion of the charge has been carried onto the molding-compartment and there been compressed. A brick is, as shown, dis charged after its first compression. The bend in the sinuous groove on the circular disk D is about to approach the ejecting-lever and move the molded brick along the brick-slide toward the second compressingcompartment. The molding-block is near the outer extremity of its travel, as is also the molding-ram. The compressing-ram is near the nearest extremity of its travel, as is also the compressing-block. Fig. 2 is a perspective view of one side of the machine. The molding ram and block are nearer the inner extremity of their travel than the outer, the compressing ram and block being nearer their outer extremities than their inner. Fig. 3 is also a perspective view of the machine look ing at it from the ejector-lever side. Fig. 4 is a side elevation, on an enlarged scale, of the crank-shaped rod moving the compression-block.

Similar letters of reference indicate similar or corresponding parts where they occur in the several Views.

Our invention includes a base-plate A, one end of which is hereinafter called the shaft end A. Upon the shaft end A are bearings B. In these bearings turns a shaft O, which shiaft overhangs the said hearings on each S1 6. aforesaid shaft is situated a fast and a loose driving-pulley or other suitable driving-gear. On the other overhanging end C is attached a circular disk D. In the circumference of On one overhanging end C of the this is a sinuous groove or recess D, hereinafter referred to.

Between the two bearings and on the side of the machine nearest to the circular disk is an eccentric E. (See Fig. 2.) Around this eccentric is an eccentric-strap E, to which is attached the inner end of an eccentric-rod E The back end of the rod is pivoted to a ram F, hereinafter called the moldingram. This ram moves backward and forward within the guide-case L. On each side of the said eccentric and attached to the shaft are disk cams H. On each side of each cam is the leg H of a forked cam-rod H The legs H or inner ends of each cam-rod reciprocate in guides in the top of guide-pillars J, attached to the base-plate. Between each pair of forked legs H is situated a roller H so that a rolling contact with the disk cam is formed.

Each guide J is provided with upper and lower rollers J and J (See Fig. 2.) Mounted on the shaft, one on each side of the eccentric and between the said eccentric and the camdisk, are two smaller return-cams K. (See Fig. 1.) Each one of these engages with a stud K, having a roller K thereon protruding from the inner forked-leg H of the cam-rod H The object of the said cams is the quick return of the cam-rods H At the outer end of each cam-rod are vertical extensions H To these are attached adjusting-bolts H At the outer extremity of each adjusting-bolt and connected to the bolts by a link H (see Fig. 3) is the outer end of a pin H The inner end of the said pin passes through the walls of the moldingblock guide-case L and is attached to the molding-block L (seen in dotted lines in Fig. 1) inside the said case. The said pin works in slots L Situated on the box end of the base-plate is a mold ing-ram guide-case L. In line with this is the molding-compartment L. Inside the case and the compartment moves the ram F hereinbefore referred to. Situated above the top of the moldingra1n guidecase is a feed-hopper L Into this the material to be compressed is charged. The section of the guidecase and molding-compartment is equal to the length and Width of a brick. Across the passage-way formed between the molding-compartment L and the molding-block guide-case L is a brick-discharge passage M.

On the same side of the box as the circular disk D, before referred to, is placed an ejector N. This has upon its striking end a head N of felt or any other material which may be saturated with oil or other liquid. The said ejector works in guides N and is moved backward and. forward by an ejecting-lever N. The said ejecting-lever is pivoted by a pin N to a pillar N attached to the baseplate of the machine. The inner end, by a roller mounted on a pin N, (see Fig. 1,) engages with the groove in the circular disk D and the other end engages with the ejector l.

On the shaft end nearest the driving-pulley, but inside the adjacent bearing, is a small eccentric 0. Around this is an eccentrio-strap O, to which is attached the inner end. of an eccentric-rod The outer end of this eccentric-rod is pivoted to the com.- pressor-ram O, which moves backward and forward. in the guid e-case O Separated from the guide-case O by a brick-discharge passage M is the second compressing-compartment and compressing-block guide 0".

Two studs or pins 0 protrude from the sides of the compressor-ram 0 Connected to these studs or pins are the inner ends of crank-shaped rods 0 These inner ends have slots 0 which slots work longitudinally on the said studs. The outer end of the said. cranked rods 0 are pivoted to the pin 0 protruding from a compressor-block 0. (Shown in dotted lines in Fig. 1.) The said compressor-block O is moved backward and forward within the compressingcompartment 0 and its outer movement from the said compressing-compartment is prevented by the back of such case, or, if an open case be used, by a limit-stop of any character.

Suitable scrapers to scrape any fins formed while the bricks are being compressed are placed where necessary. Suitable oil-pads are also provided if and where necessary.

Between the brick-discharge passages M is placed a bridge-piece Q. Upon one or both sides of the said bridgepiece may be placed an oil-pad, or suitable guides may be provided. On the side of the compressing-compartment is a brick-discharge platform R. This platform has scrapers R and, if necessary, a guide R Attached to the outer stud O on the compressor-ram O is a pusherarm R. To this is attached a head or plate R This pusher-ar1n as it moves outwardly forces the bricks down the dischargeplatform R. I

The ramming-faces of the rams and blocks are provided with metallic liners. Both the molding and compressing compartments may also be provided with liners.

Situated between the shaft end and the box end of the base-plate is a transverse guide 0 rocking shaft T. To this is attached the lower end of an arm T on the upper arm of which is laced the ramming-plate T There are a so attached to the said rocking shaft the inner ends of arms T and T (See Fig. 2.) The outer ends of said shaft make contact with a stud or projection T which extends from the shaft C. When the stud or projection T strikes the upper arm T, the ramming-plate is forced down upon the clay, whereas when it strikes the lower one T it lifts the said rammingplate.

The cycle of operations with our invention is as follows: The clay is dropped into the feed-hopper L The ramming-plate T then descends on top of it' The mo1ding-rarn F moves outwardly and forces a charge past the hopper-mouth toward the molding-com partment L At the same time the molding-block L, by the disk-cams H and camrods H is being drawn inwardly toward the said charge within the molding-compartment L. The said molding-block L passes over the brick-discharge passage M. The correct degree of compression having been arrived at, the ram' block L reverses its motion and also moves outwardly, the rods H being moved backward by the return-cams K. A brick is thus left in the brick-discharge passage M. The ejector N then forces it onto the brick-slide Q and retires. When the second brick is forced from the molding-compartment and is pressed by the ejector N, the first brick is moved on the slide Q. The third brick forces the first opposite the mouth of the compressing-compartment and compressor- The compressor-ram O forces it into the said compartment 0 and it is there retarded by the compressor-block O and by the limit-stop in the said compartment if an open case is used. After this second cornpression the compressor-ram 0 moves inwardly, and as it does so the studs or ins O drag the crank-rods O inwardly, tiereby also drawing inwardly the compressor-block O. This leaves the brick on the brick-disch( rge passage M, and on the neXt movement F still moves outwardly. The

of the ejector N the said brick is pushed to the brick-discharge platform R. From this it is forced outward by the plate R on the brick-moving arm R.
